bracket 3 is further provided with axial and longitudinal slots 18 and 19 respectiveeither one of which is adapted to receive the ball 21-. c In the slot 19 is mounted a roller 2 the outer rim of which is in alinernent.

with the axis of the aperture 18., v

Numeralll designates a circular drum or spool having a deep recess 12 into the bottom of which leads aperture 13. The drum, or spool 11 is further provided with projections 14 and 15 at its outer and inner sidesrespectively. The inner projection 15 is provided with indentations 16. Passing centrally through thecor'e'of the drum,'or spool, is a circular boring 17.

On the periphery of the drum 11 there is formed a notch 27 This notch is socut that one side wall thereof is substantially perpendicular to the axis of the drum and the other side wall is disposed at an angle to the said stantial width and depth, there iswound a cord 28. I

Now, to assemble and put into use and operation my device, when used'in'connection with the raising and lowering of a curtain, it is only necessary to first fix the brackets 2 and 3 inplace. Bracket 3, having flanges 29 and 30, and apertures 18 and 20 at both ends,

renders it reversible and adaptable to practically any location or situation.

v The brackets being in place, the thimbles are slipped on the curtain-pole and the pole, with the curtain 'TOIl it, is mounted. on the brackets, care beingta'ken that the thimble I "of the structure shown at Fig. 2 should be mounted in bracket 3. Then oneend of the cord 28 is pulled through aperture 13 until a knot, at the otherend of the cord stops up against the outer opening of the aperture. The cord is then wound around the axle of recess 12, and the other end. of the cord is passed through aperture 19, over the roller 22 and down through aperture 18 and alongside the window j amb as shown at 31, Fig.1.'

This being done, the end of the thimble in bracket-13 is lifted up and the drum, or spool, 11 is slippedin the opening 8 ofthe bracket, projection 24 passing through the central And, it is also provided with slots 20 4 bore of the spool, and lugs 26 fitting in depressions 16; The nut 25 is then threaded in place,'and the ball 21 is dropped in the hole20. 7

Now, to raise the curtain, it is only necessary to pull the cord-end 31 downward,

causing the ball 21 to play up and down in V 'slot 20, and the curtain to be rolled up on the pole 4. When it is desired to stop the curtain'at any point, the rope is held fast'an'd then pulled upand down slowly, until the ball lodges in not-ch27 as shown at Fig. 5.

This looks the drum againstrotation and the curtain is held securely at the desired place. To um-011, or lower the curtain, therope fis jerked gently, thus dislodging the ball from the notch and the curtain is allowed to roll down force of gravity, and again,by

holding'up on the rope the ball relodges in the'notch and the movement of the curtain stops.

thimbleis formed with a single square'p'ro- 'jection 32 at the center of its outer surface.

This projection 32, has a threaded boreand The structure shown at Fig.7, is similar to that at Fig. 2,with the exception that the fits in a recess 33 of'the drum, and its" threaded bore comes in alinement with the axial bore of the drum. A threadedbolt 34 passes through the axial bore of the drum and threads into the threaded recess of the projection 32, thus holding the drum and thimble together.

the bracket 7 in this structure. The .rest of the structure is substantiallyfthe same as that shown at Fig. 71

j V In this. structure I also provide detachable side plates '35 and 36 for,

Numeral 37,:at Fig. 8, designates apin;

which, passing through acrossthe top 'of'the opening 20, serves as a keeper to preventthe ball 21 from jumping out of'its recess. WVhen the diameterlor" the drum, or'spool,

is comparatively large, it may befprovided J with any desirable number of; notches. This will enable it to stop at closer intervalsbecause it will afi'ord more places] at which the ball can lock it in place;

" Theform ofthedevice shown at Fi s, 9

and 10. isadapted to, lift or lower, or aul 7 .11-5 7 the bracket I use a casing38 which. is procompact weights in bulk. Here, instead of .vided with detachable socket pieces 39 v on which is mounted a drum'40. This drum is provided with two wide and deep recesses 41 and 42. It will .be'noted that one of these recesses is deeper than the other,thus afio'rd: ing a differential in the diameters or th'e two winding compartments of the drum. 7 That is, the diameter of one compartment is larger than the other. .On each of these compartments is wound a rope one counter-wisejo the, other, so that winding the one unwinds the other, and vice versa. l At the top'of the casing 38 ishinged a hoop or bale 42 at center of which is swivelly connected a loop or ring 43 which is held stationary by means indicated by numeral 44, which may be either a hook, cable or rope.

When this form of the device is secured in place, the load to be lifted, or lowered, or

panying drawings that I have invented a new and useful improvement in Windlass mechanisms, and as is badly needed for the raising and lowering of curtains and loads.

My invention is also simple in construction and operat on, durable and efficient in service, because it eliminates the use of springs.

The same can also be cheaply manufactured and sold at a reasonable price.

It is also obvious that while I have herein described what I have found to be very practical embodiment and application ofmy invention, the specific details of construction and configuration of parts may be modified, and the invention itself may be applied to other uses without departing from the spirit and scope thereof as defined in the appended claims.

Having now set forth my invention in the foregoing specification and having further,

illustrated the same in the accompanying drawings, what I claim as my own and desire to secure .by Letters Patent of the United States is: a 7

1. In a Windlass mechanism' for lifting, lowering or hauling a load,'thev combination locking the drum against of a stationary casing, a drum supported in the casing, wide recesses on the drum, said recesses being of diiferentd'epths andseparated into compartments by flanges; a rope wound on one of the recesses for causing the drum to rotate and a winding means counter to the said rope on another of the recesses for moving a load relative to the drum when said drum is" rotating ,with a notch on one of the flanges of the drum, a slotinthecascome in alinement with' each other forming arecessbetween thecasilig andthe drum, and a ball in the slot which, when the drum rotates slowly, lodges in the notch thereby further rotation relative to the casing.

A device for hoisting, lowering or haul} ing a load, comprising a stationaryhollow' casing, said casing having. a: slot disposed; I verticallythereof and a slot disposed horizontally thereof; the vertical slot extending .the full length of the casing and the horizontal slot extending from one side into the,

hollow of theycasing; a wheel rotatably .ing, said notch and slot being adapted to mounted in'the horizontal slot, the rim of said wheel being grooved and the axis of the vertical slot forming a tangent to the groove of the wheel; a drum mounted in the casing,

a rope passing-through the vertical slot and outside of the casing and-the other portion over the wheel in the-horizontal slot a por- Y I tion of said rope being permitted to hang being wound on a portion of the drum; fiexi- V:

ble means wound on another portion of the Q drum and counterwise to the said rope; and

spherical locking meansco-operating 1 with the drum and the casing for automatically stopping and releasing the drum.

In testimony whereof, I have hereuntoset my hand this 28th day of December, 1926.
